请参见图1,图1是本公开实施例可应用的一种网络系统的结构图,如图1所示,包括终端11和网络侧设备12,其中,终端11和网络侧设备12之间可以进行通信。
在本公开实施例中,终端11也可以称作用户设备(User Equipment,UE)。在实际应用中,终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant,PDA)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备等。网络侧设备12可以是基站、中继或接入点等。
为了方便理解,以下对本公开实施例涉及的一些内容进行说明:
一、新两步随机接入(2-Step Random Access Channel,2-Step RACH)。
如图2所示,两步随机接入过程可以包括以下步骤:
步骤201、网络侧设备给终端配置新两步随机接入的配置信息,配置信息可以包括:消息(Message,Msg)A和MsgB对应的发送资源信息。
之后,终端触发2-step RACH过程,执行步骤202。
步骤202、终端将随机接入请求信息(MsgA)发送给网络侧设备。
具体实现时,MsgA可以仅包括数据信道(如,物理上行共享信道(Physical Uplink Shared Channel,PUSCH)),或同时包括数据信道(如,PUSCH)和控制信道(如,物理随机接入信道(Physical Random Access Channel,PRACH))。
步骤203、网络侧设备发送确认信息(MsgB)给终端。

二、相关技术中的4步随机接入过程(4-step RACH)。
终端的随机接入过程包括:基于竞争的的随机接入过程(4-step RACH);基于非竞争的随机接入过程。
对于“基于竞争的随机接入过程”,UE发送Msg1(随机接入请求)给网络侧。网络侧接收到Msg1后给UE发送Msg2(随机接入响应(Random Access Response,RAR)消息)给UE,该消息中携带了上行授权(Uplink Grant)信息。UE根据Msg2中的Uplink Grant,执行媒体接入控制(Medium Access Control,MAC)层组包功能生成MAC协议数据单元(Protocol Data Unit,PDU),并将该MAC PDU存储在Msg3缓存中,然后UE将Msg3缓存中的MAC PDU通过混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)进程进行发送。网络侧接收到Msg3后发送Msg4(如,竞争解决标识)给UE。UE接收到Msg4判断是否竞争解决成功,如果成功则随机接入过程成功,否则重新发起随机接入过程。对于重新发起的随机接入过程,当UE又接收到Msg2中的Uplink Grant后,UE直接从Msg3缓存中取出之前存储的MAC PDU并通过HARQ进程进行发送。UE在随机接入过程完成后会清空随机接入过程的Msg3传输的HARQ缓存。

具体实现时,接收配置信息可以是接收网络侧设备发送的配置信息。
需要说明的是,在实际应用中,终端在每次发送随机接入请求信息之前,并不一定需要接收所述配置信息。换句话说,终端在接收到所述配置信息之后,可以基于所述配置信息发送多次随机接入请求信息。这样,可以节约信令开销。
在本实施例中,可选地,所述在第一随机接入请求资源上发送随机接入请求信息之前,所述方法还包括以下至少一项:
按照第一选择规则,从所述N种随机接入过程类型对应的随机接入请求资源中选择所述第一随机接入请求资源;
按照第二选择规则,从所述N种随机接入过程类型中选择所述第一随机接入过程类型。
进一步地,所述按照第二选择规则,从所述N种随机接入过程类型中选择所述第一随机接入过程类型,可以包括以下至少一项:
根据信号的测量门限值,从所述N种随机接入过程类型中选择所述第一随机接入过程类型;
根据数据的大小,从所述N种随机接入过程类型中选择所述第一随机接入过程类型;
根据随机数,从所述N种随机接入过程类型中选择所述第一随机接入过程类型;
根据随机接入过程类型的优先级,从所述N种随机接入过程类型中选择所述第一随机接入过程类型。
为方便理解,以下分别说明如下:
第一场景、根据信号的测量门限值,从所述N种随机接入过程类型中选 择所述第一随机接入过程类型。
在第一场景中,一种实现方式中,终端可以预先设置信号的测量门限值,以及信号测量值与信号的测量门限值的各比较结果分别对应的随机接入过程类型。这样,终端可以将测量得到的信号测量值与信号的测量门限值进行比较,并根据该比较结果对应的随机接入过程类型确定所述第一随机接入过程类型。
示例性地,假设网络侧指示或协议约定小区1的参考信号接收功率(Reference Signal Received Power,RSRP)门限值为-80分贝毫瓦(dBm),第一比较结果对应随机接入过程类型1,第二比较结果对应随机接入过程类型2,其中,第一比较结果为:小区1的RSRP测量值小于小区1的RSRP测量门限值,第二比较结果为:小区1的RSRP测量值大于或等于小区1的RSRP测量门限值。当小区1的RSRP测量值超过-80dBm时,终端选择随机接入过程类型2作为所述第一随机接入过程类型。
另一种实现方式中,终端可以预先设置各随机接入过程类型对应的信号的测量门限值,若信号测量值大于某信号的测量门限值,则终端可以根据该信号的测量门限值对应的随机接入过程类型确定所述第一随机接入过程类型。
示例性地,假设随机接入过程类型1对应的信号的测量门限值为-80dBm,随机接入过程类型2对应的信号的测量门限值为-90dBm。若信号测量值为-85dBm,则终端可以将随机接入过程类型2作为所述第一随机接入过程类型。
第二场景、根据数据的大小,从所述N种随机接入过程类型中选择所述第一随机接入过程类型。
在第二场景中,一种实现方式中,终端可以预先设置数据的大小的门限值,以及待发送或待接收的数据的大小与数据的大小的门限值的各比较结果分别对应的随机接入过程类型。这样,终端可以将在随机接入过程中待发送或待接收的数据的大小与数据的大小的门限值进行比较,并根据该比较结果对应的随机接入过程类型确定所述第一随机接入过程类型。
示例性地,假设网络侧指示或协议约定小区1的数据的大小的门限值为56比特(Bit),第一比较结果对应随机接入过程类型1,第二比较结果对应随机接入过程类型2,其中,第一比较结果为:终端在随机接入过程中待发 送的数据的大小小于56Bit,第二比较结果为:终端在随机接入过程中待发送的数据的大小大于或等于56Bit。当终端在随机接入过程中待发送的数据的大小为60Bit时,终端选择随机接入过程类型2作为所述第一随机接入过程类型。
另一种实现方式中,终端可以预先设置各随机接入过程类型对应的数据的大小的门限值,若待发送或待接收的数据的大小大于某数据的大小的门限值,则终端可以根据该数据的大小的门限值对应的随机接入过程类型确定所述第一随机接入过程类型。
示例性地,假设随机接入过程类型1对应的数据的大小的门限值为50Bit,随机接入过程类型2对应的数据的大小的门限值为70Bit。若终端在随机接入过程中待发送的数据的大小为60Bit,则终端可以将随机接入过程类型1作为所述第一随机接入过程类型。
第三场景、根据随机数,从所述N种随机接入过程类型中选择所述第一随机接入过程类型。
在第三场景中,一种实现方式中,终端可以预先设置数值门限值,以及随机数与数值门限值的各比较结果分别对应的随机接入过程类型。这样,终端可以将得生成的随机数与数值门限值进行比较,并根据该比较结果对应的随机接入过程类型确定所述第一随机接入过程类型。
示例性地,假设网络侧指示或协议约定小区1的数值门限值为0.5,第一比较结果对应随机接入过程类型1,第二比较结果对应随机接入过程类型2,其中,第一比较结果为:终端生成的随机数小于0.5,第二比较结果为:终端生成的随机数大于或等于0.5。当终端生成的随机数为0.6时,终端选择随机接入过程类型2作为所述第一随机接入过程类型。
另一种实现方式中,终端可以预先设置各随机接入过程类型对应的数值门限值,若终端生成的随机数大于某数值门限值,则终端可以根据该数值门限值对应的随机接入过程类型确定所述第一随机接入过程类型。
示例性地,假设随机接入过程类型1对应的数值门限值为1,随机接入过程类型2对应的数值门限值为2。若终端在随机接入过程中随机数为1.5,则终端可以将随机接入过程类型1作为所述第一随机接入过程类型。
第四场景、根据随机接入过程类型的优先级,从所述N种随机接入过程类型中选择所述第一随机接入过程类型。
在第四场景中,终端可以预先设置各随机接入过程类型对应的优先级,并根据各随机接入过程类型对应的优先级,从所述N种随机接入过程类型中选择所述第一随机接入过程类型。可选地,终端可以预先选择优先级最高的随机接入过程类型作为所述第一随机接入过程类型。
示例性地,假设随机接入过程类型1对应的优先级高于随机接入过程类型2对应的优先级,则终端可以将随机接入过程类型1作为所述第一随机接入过程类型。
此外,需要说明的是,在终端基于上述一个场景选择到的随机接入过程类型的数量大于1的情况下,一种方式中,终端可以从选择到的多个随机接入过程类型中随机选择一个随机接入过程类型,作为所述第一随机接入过程类型。
另一种方式中,终端可以结合上述4个场景中的至少两个场景,从所述N种随机接入过程类型中选择所述第一随机接入过程类型。
示例性地,终端可以结合场景一和场景二,从所述N种随机接入过程类型中选择所述第一随机接入过程类型。也就是说,终端可以根据信号的测量门限值和数据的大小,从所述N种随机接入过程类型中选择所述第一随机接入过程类型。
假设网络侧指示或协议约定小区1的RSRP门限值为-80分贝毫瓦(dBm),第一比较结果对应随机接入过程类型1和随机接入过程类型2,第二比较结果对应随机接入过程类型3和随机接入过程4,其中,第一比较结果为:小区1的RSRP测量值小于小区1的RSRP测量门限值,第二比较结果为:小区1的RSRP测量值大于或等于小区1的RSRP测量门限值。
假设网络侧指示或协议约定小区1的数据的大小的门限值为56Bit,第三比较结果对应随机接入过程类型1和随机接入过程类型3,第四比较结果对应随机接入过程类型2和随机接入过程4,其中,第三比较结果为:终端在随机接入过程中待发送的数据的大小小于56Bit,第二比较结果为:终端在随机接入过程中待发送的数据的大小大于或等于56Bit。
当小区1的RSRP测量值超过-80dBm时,终端可以选择随机接入过程类型3或随机接入过程类型4作为所述第一随机接入过程类型。此时,终端可选择作为所述第一随机接入过程类型的随机接入过程类型的数量大于1。
因此,进一步地,终端判定终端在随机接入过程中待发送的数据的大小与数据的大小的门限值的比较结果。由于终端在随机接入过程中待发送的数据的大小为60Bit,终端选择随机接入过程类型4作为所述第一随机接入过程类型。
通过上述方式选择的第一随机接入过程类型可以满足终端的实际需求,从而可以提高随机接入过程的资源利用效率。
另外,对于按照所述第一选择规则,选择所述第一随机接入请求资源,说明如下:
由前述内容可知,所述N种随机接入过程类型对应的随机接入请求资源可以包括一项或多项资源,同样地,所述第一随机接入请求资源也可以包括一项或多项资源。在所述第一随机接入请求资源包括多项资源的情况下,终端可以按照第一选择规则,选择所述第一随机接入请求资源中的各项资源。
可选地,所述按照第一选择规则,从所述N种随机接入过程类型对应的随机接入请求资源中选择所述第一随机接入请求资源,可以包括:
根据信号的测量门限值,从所述N种随机接入过程类型对应的随机接入请求资源中选择所述第一随机接入请求资源。
为方便理解,以下以根据信号的测量门限值,选择随机接入请求对应的上行载波进行示例说明。对于其他资源,其选择原理类似,此处不再赘述。
具体实现时,一种实现方式中,终端可以预先设置信号的测量门限值,以及信号测量值与信号的测量门限值的各比较结果分别对应的所述第一随机接入请求资源中的上行载波。这样,终端可以将测量得到的信号测量值与信号的测量门限值进行比较,并根据该比较结果对应的所述第一随机接入请求资源中的上行载波确定所述第一所述第一随机接入请求资源中的上行载波。
示例性地,假设网络侧指示或协议约定小区1的参考信号接收功率门限值为-80dBm,第一比较结果对应上行载波1,第二比较结果对应上行载波2,其中,第一比较结果为:小区1的RSRP测量值小于小区1的RSRP测量门 限值,第二比较结果为:小区1的RSRP测量值大于或等于小区1的RSRP测量门限值。当小区1的RSRP测量值超过-80dBm时,终端选择上行载波2作为所述第一随机接入请求资源中的上行载波。
另一种实现方式中,终端可以预先设置各上行载波对应的信号的测量门限值,若信号测量值大于某信号的测量门限值,则终端可以根据该信号的测量门限值对应的上行载波确定所述第一上行载波。
示例性地,假设上行载波1对应的信号的测量门限值为-80dBm,上行载波2对应的信号的测量门限值为-90dBm。若信号测量值为-85dBm,则终端可以将上行载波2作为所述第一随机接入请求资源中的上行载波。
在某些实施方式中,终端可以根据信号的测量门限值、数据的大小、随机数和资源优先级中的至少一项,从所述N种随机接入过程类型对应的随机接入请求资源中选择所述第一随机接入请求资源中的各项资源。其选择原理与选择所述第一随机接入过程类型类似,具体可参考上述关于选择所述第一随机接入过程类型的描述,此处不再赘述。
通过上述方式选择的第一随机接入请求资源可以满足终端的实际需求,从而可以提高随机接入过程的资源利用效率。
在实际应用中,终端可以按照第一选择规则选择所述第一随机接入请求资源,和/或,按照第二选择规则选择所述第一随机接入过程类型,以下对不同的实施方式进行说明。
实施方式一、终端按照第一选择规则选择所述第一随机接入请求资源,不按照第二选择规则选择所述第一随机接入过程类型。
在实施方式一中,终端按照第一选择规则选择所述第一随机接入请求资源之后,可以从所述第一随机接入请求资源对应的随机接入过程类型中选择所述第一随机接入过程类型。
具体地,若所述第一随机接入请求资源对应的随机接入过程类型的数量为1,则可以直接将该随机接入过程类型选择作为所述第一随机接入过程类型。
若所述第一随机接入请求资源对应的随机接入过程类型的数量大于为1,则可以随机从该多个随机接入过程类型选择一个随机接入过程类型作为所述 第一随机接入过程类型。
需要说明的是,在所述第一随机接入请求资源包括多项资源的情况下,所述第一随机接入请求资源对应的随机接入过程类型为:所述第一随机接入请求资源中各项资源均对应的随机接入过程类型。
示例性地,假设所述第一随机接入请求资源包括上行载波1和下行信号1,上行载波1对应的随机接入过程类型包括随机接入过程类型1和随机接入过程类型2,下行信号1对应的随机接入过程类型包括随机接入过程类型1和随机接入过程类型3,则终端只可以将随机接入过程类型1作为所述第一随机接入过程类型,而不能把随机接入过程类型2或随机接入过程类型3作为所述第一随机接入过程类型。
通过实施方式一选择的随机接入过程类型必定与选择的随机接入请求资源对应,因此,可以提高随机接入过程类型选择的效率。
实时方式二、终端按照第二选择规则选择所述第一随机接入过程类型,不按照第一选择规则选择所述第一随机接入请求资源。
在实施方式二中,终端按照第二选择规则选择所述第一随机接入过程类型之后,可以从所述第一随机接入过程类型对应的随机接入请求资源中选择所述第一随机接入请求资源。
具体地,若所述第一随机接入过程类型对应的随机接入请求资源中某项资源的数量为1,则可以直接选择该资源。
若所述第一随机接入过程类型对应的随机接入请求资源中某项资源的数量大于1,则可以随机从该多个资源中选择一个资源。
通过实施方式二选择的随机接入请求资源必定与选择的随机接入过程类型对应,因此,可以提高随机接入请求资源选择的效率。
实时方式三、终端按照第一选择规则选择所述第一随机接入请求资源,并按照第二选择规则选择所述第一随机接入过程类型。
在实施方式三中,可进一步限定按照第一选择规则选择所述第一随机接入请求资源,以及按照第二选择规则选择所述第一随机接入过程类型的先后顺序。
可选地,所述第一随机接入请求资源包括M项资源,M为正整数;
所述方法还包括以下任意一项:
在按照所述第一选择规则选择所述第一随机接入请求资源中的K项资源之后,按照所述第二选择规则,从所述N种随机接入过程类型中选择所述第一随机接入过程类型,K为小于或等于M的正整数;
在按照所述第二选择规则选择所述第一随机接入过程类型之后,按照所述第一选择规则,从所述N种随机接入过程类型对应的随机接入请求资源中选择所述第一随机接入请求资源。
为方便理解,分别说明如下:
第一实现方式、在按照所述第一选择规则选择所述第一随机接入请求资源中的K项资源之后,按照所述第二选择规则,从所述N种随机接入过程类型中选择所述第一随机接入过程类型。即先选择K项资源,后选择随机接入过程类型。
在第一实现方式中,可选地,在K小于M的情况下,所述按照所述第二选择规则,从所述N种随机接入过程类型中选择所述第一随机接入过程类型之后,所述方法还包括:
按照所述第一选择规则选择所述第一随机接入请求资源中除所述K项资源之外的其他资源。
为方便理解,以所述第一随机接入资源包括:上行载波、下行信号和编码资源为例进行说明。
一种方式中,终端可以在按照第一选择规则选择所述第一随机接入资源包括的全部资源,即上行载波、下行信号和编码资源之后,按照所述第二选择规则,从所述N种随机接入过程类型中选择所述第一随机接入过程类型。
另一种方式中,终端可以在按照第一选择规则选择所述第一随机接入资源包括的部分资源,如上行载波之后,按照所述第二选择规则,从所述N种随机接入过程类型中选择所述第一随机接入过程类型,再按照第一选择规则选择所述第一随机接入资源包括的剩余资源,如下行信号和编码资源。
在第一实现方式中,终端可以至少通过以下两种方式按照第二选择规则,选择所述第一随机接入过程类型。
方式一、终端可以按照第二选择规则,直接从所述N种随机接入过程类 型中选择所述第一随机接入过程类型。在方式一中,所述第一随机接入过程类型的选择,与所述第一随机接入请求资源的选择相互独立。
方式二、可选地,所述按照第二选择规则,从所述N种随机接入过程类型中选择所述第一随机接入过程类型,包括:按照第二选择规则,从与所述第一随机接入请求资源对应的随机接入过程类型中选择所述第一随机接入过程类型。
在方式二中,所述第一随机接入过程类型的选择与所述第一随机接入请求资源选择的结果相关,所述第一随机接入过程类型必定与所述第一随机接入请求资源对应,因此,可以提高所述第一随机接入过程类型选择的效率。
在实际应用中,由于在方式一中,由于随机接入过程类型的选择与随机接入请求资源的选择相互独立,因此,通过上述方式一选择的接入过程类型与随机接入请求资源可能不对应。
在通过上述方式一选择的接入过程类型与随机接入请求资源不对应的情况下,终端需要重新选择随机接入过程类型,以使得最后选择的随机接入过程类型与先选择的随机接入请求资源对应。具体地,可以通过上述方式二重新选择随机接入过程类型。
可选地,所述按照第二选择规则,从与所述第一随机接入请求资源对应的随机接入过程类型中选择所述第一随机接入过程类型之前,所述方法还包括:
按照所述第二选择规则,从所述N种随机接入过程类型中选择第二随机接入过程类型;
所述按照第二选择规则,从与所述第一随机接入请求资源对应的随机接入过程类型中选择所述第一随机接入过程类型,包括:
在所述第二随机接入过程类型对应的随机接入请求资源与所述K项资源没有重叠的情况下,按照第二选择规则,从所述K项资源对应的随机接入过程类型中选择所述第一随机接入过程类型。
具体实现时,在所述第二随机接入过程类型对应的随机接入请求资源中的一项或多项资源与所述K项资源中相应的资源没有重叠的情况下,即可视为所述第二随机接入过程类型对应的随机接入请求资源与所述K项资源没有 重叠。
示例性地,假设K项资源包括:上行载波和下行信号,且K项资源的上行载波为上行载波1,下行信号为下行信号1;而所述第二随机接入过程类型对应的随机接入请求资源中的上行载波为上行载波2,下行信号为下行信号1。则终端可以视所述第二随机接入过程类型对应的随机接入请求资源与所述K项资源没有重叠。
第二实现方式、在按照所述第二选择规则选择所述第一随机接入过程类型之后,按照所述第一选择规则,从所述N种随机接入过程类型对应的随机接入请求资源中选择所述第一随机接入请求资源。即先选择随机接入过程类型,后选择随机接入请求资源。
在第二实现方式中,终端可以至少通过以下两种方式按照第一选择规则,选择所述第一随机接入请求资源。
方式一、终端可以按照第一选择规则,直接从所述N种随机接入过程类型对应的随机接入请求资源中选择所述第一随机接入请求资源。在方式一中,所述第一随机接入过程类型的选择,与所述第一随机接入请求资源的选择相互独立。
方式二、可选地,所述按照第一选择规则,从所述N种随机接入过程类型对应的随机接入请求资源中选择所述第一随机接入请求资源,包括:按照第一选择规则,从与所述第一随机接入过程类型对应的随机接入请求资源中选择所述第一随机接入请求资源。
在方式二中,所述第一随机接入请求资源的选择与所述第一随机接入过程类型选择的结果相关,所述第一随机接入请求资源必定与所述第一随机接入过程类型对应,因此,可以提高所述第一随机接入请求资源选择的效率。
在实际应用中,由于在方式一中,由于随机接入过程类型的选择与随机接入请求资源的选择相互独立,因此,通过上述方式一选择的接入过程类型与随机接入请求资源可能不对应。
在通过上述方式一选择的接入过程类型与随机接入请求资源不对应的情况下,终端需要重新选择随机接入请求资源,以使得最后选择的随机接入请求资源与先选择的随机接入过程类型对应。具体地,可以通过上述方式二重 新选择随机接入请求资源。
可选地,所述按照第一选择规则,从与所述第一随机接入过程类型对应的随机接入请求资源中选择所述第一随机接入请求资源之前,所述方法还包括:
按照第一选择规则,从所述N种随机接入过程类型对应的随机接入请求资源中选择第二随机接入请求资源;
所述按照第一选择规则,从与所述第一随机接入过程类型对应的随机接入请求资源中选择所述第一随机接入请求资源,包括:
在所述第二随机接入请求资源与所述第一随机接入过程类型对应的随机接入请求资源没有重叠的情况下,按照第一选择规则,从所述第一随机接入过程类型对应的随机接入请求资源中选择所述第一随机接入请求资源。
具体实现时,在所述第二随机接入请求资源中的一项或多项资源与所述第一随机接入过程类型对应的随机接入请求资源中相应的资源没有重叠的情况下,即可视为所述第二随机接入请求资源与所述第一随机接入过程类型对应的随机接入请求资源没有重叠。
示例性地,假设所述第二随机接入请求资源中的上行载波为上行载波2,下行信号为下行信号1,而所述第一随机接入过程类型对应的随机接入请求资源中的上行载波为上行载波1,下行信号为下行信号1,则可以视所述第二随机接入请求资源与所述第一随机接入过程类型对应的随机接入请求资源没有重叠。
参见图4,图4是本公开实施例提供的配置方法的流程图。本公开实施例的配置方法应用于网络侧设备。
如图4所示,配置方法可以包括以下步骤:

需要说明的是,本实施例作为与上述方法实施例对应的网络侧设备的实施方式,因此,可以参见上述方法实施例中的相关说明,且可以达到相同的有益效果。为了避免重复说明,在此不再赘述。
需要说明的是,本公开实施例中介绍的多种可选的实施方式,彼此可以相互结合实现,也可以单独实现,对此本公开实施例不作限定。
为方便理解,示例说明如下:
步骤一、网络侧根据随机接入过程类型配置对应的随机接入请求资源配置信息。其中,该“不同类型的随机接入过程”包括以下至少2种:
随机接入过程类型1:在4步随机接入过程的第3条消息发送数据;
随机接入过程类型2:在2步随机接入过程的第1条消息(如MsgA)发送数据;
随机接入过程类型3:在4步随机接入过程的第4条消息接收数据;
随机接入过程类型4:在2步随机接入过程的第2条消息(如MsgB)接收数据;
随机接入过程类型5:普通的随机接入过程(如,普通的4步随机接入(即,不能在Msg3中发送用户面数据的随机接入过程);普通的2步随机接入(即,不能在MsgA中发送用户面数据的随机接入过程))。
其中,该“随机接入过程类型1”和“随机接入过程类型2”的随机接入过程的类型又可以分为:
随机接入过程类型6:UE通过数据承载(如,数据无线承载(Data Radio Bearer,DRB))发送数据;
随机接入过程类型7:UE通过信令承载(如,数据无线承载(Signaling Radio Bearer,SRB))发送数据。
应理解的是,随机接入过程类型6和随机接入过程类型7为“随机接入过程类型1”和“随机接入过程类型2”子类型。
其中,该“随机接入过程类型3”和“随机接入过程类型4”的随机接入过程的类型又可以分为:
随机接入过程类型8:通过数据承载(如,DRB)接收数据;
随机接入过程类型9:通过信令承载(如,SRB)接收数据。
应理解的是,随机接入过程类型8和随机接入过程类型9为“随机接入过程类型3”和“随机接入过程类型4”子类型。
其中,该“随机接入过程类型1”和“随机接入过程类型2”发送的数据(和/或“随机接入过程类型3”和“随机接入过程类型4”接收的数据)可以进一步限定为UE的用户面数据(如,DRB数据和/或QoS flow的数据)。
对于上述方法,该“随机接入请求资源配置信息”包括以下至少一项:
随机接入请求对应的时频资源(如,RO1或PO1);
随机接入请求对应的下行信号(如,CSI-RS-1和/或SSB-1);
随机接入请求对应的小区(如,Cell-1);
随机接入请求对应的上行载波(如,SUL或NUL);
随机接入请求对应的编码资源(如,PRACH信道的preamble码编号范围[1,10])。
其中,不同“随机接入过程类型”对应的“随机接入请求资源配置信息”可以相同或不同或部分相同。
如,不同“随机接入过程类型”对应的“随机接入请求资源配置信息”内容完全相同。
如,不同“随机接入过程类型”对应的“随机接入请求资源配置信息”内容的各信息项的内容完全不同。
如,不同“随机接入过程类型”对应的“随机接入请求资源配置信息”内容的信息项的内容部分相同(或,部分不同)。如,对应的RO(或PO)资源不同;或对应的下行信号不同;或对应的小区不同;或对应的上行载波不同;对应的PRACH信道的preamble码编号范围不同。
步骤二、根据步骤一中的配置信息,UE有上行(或下行)数据发送(或接收)的时候触发随机接入过程,同时UE需要进行随机接入过程类型的选择。则,UE随机接入过程类型选择在随机接入过程中的顺序规则为以下至少 一种:
规则1.1(先选载波,后选随机接入过程类型):当随机接入资源配置在1个小区的多个上行载波(且配置了多个上行载波的随机接入资源选择规则),且随机接入资源配置给了不同的随机接入过程类型(且配置了随机接入过程类型的选择规则)。UE先选择随机接入过程对应的载波,然后再选择随机接入过程对应的随机接入过程类型。
如,网络配置的“多个上行载波的随机接入资源选择规则”为根据信号的测量门限值选择(如,门限值为-80dBm),“随机接入过程类型的选择规则”为上行发送数据的大小小于或等于门限值则选择随机接入过程类型1,否则选择随机接入过程类型5。随机接入过程中的上行数据的门限值为56Bit。
UE在随机接入过程中,先根据网络配置的“多个上行载波的随机接入资源选择规则”选择用于随机接入信号发送的上行载波(如,UE小区1的RSRP测量值为-60dBm,则UE选择载波1),然后根据网络配置的“随机接入过程类型的选择规则”,UE随机接入过程的Msg3的大小为50Bit,则UE选择随机接入过程类型1,作为该随机接入过程。
规则1.2(先选随机接入过程类型,后选载波):当随机接入资源配置在1个小区的多个上行载波(且配置了多个上行载波的随机接入资源选择规则),且随机接入资源配置给了不同的随机接入过程类型(且配置了随机接入过程类型的选择规则)。UE先选择随机接入过程对应的随机接入过程类型,然后再选择随机接入过程对应的载波。

其中,该“多个上行载波的随机接入资源选择规则”包括根据“信号的测量门限值”进行选择(如,小区1的2个上行载波的RSRP测量门限值为-80dBm,当小区1的RSRP测量结果超过门限值则用上行载波1,否则用上 行载波2。)。
其中,该“信号的选择规则”包括根据“信号的测量门限值”进行选择(如,小区1的SSB的RSRP测量门限值为-80dBm,当小区1的SSB1测量结果超过门限值,则UE选择SSB1(即,SSB1对应的随机接入资源作为候选的随机接入资源)。)。
其中,该“随机接入过程类型的选择规则”为网络配置或协议约定。
其中,该“随机接入过程类型的选择规则”包括以下至少一种组合:
根据信号的测量门限值选择(如,UE根据网络侧指示或协议约定的小区1(或SSB1,或CSI-RS1)的RSRP的门限值(如-80dBm),当小区1(或SSB1,或CSI-RS1)的RSRP测量门限值超过-80dBm的时候,UE选择随机接入过程类型1,否则选择随机接入过程类型5);
根据上行发送数据的大小(如,UE根据网络侧指示或协议约定的小区1随机接入过程中的上行发送数据的大小的门限值(如56Bit),当UE在随机接入过程中发送的连接建立接入请求消息(或2步随机接入过程的MsgA,或4步随机接入过程的Msg3)的大小小于或等于该门限值,UE选择随机接入过程类型1,否则选择随机接入过程类型5);
同时根据信号的测量门限值和上行发送数据的大小(如,UE根据网络侧指示或协议约定的小区1(或SSB1,或CSI-RS1)的RSRP的门限值(如-80dBm)和小区1随机接入过程中的上行发送数据的大小的门限值(如,56Bit),当UE在随机接入过程中小区1(或SSB1,或CSI-RS1)的RSRP测量门限值超过-80dBm且随机接入过程中发送的连接建立接入请求消息(或2步随机接入过程的MsgA,或相关技术中的4步随机接入过程的Msg3)的大小小于或等于该门限值,UE选择随机接入过程类型1,否则选择相关技术中的随机接入过程类型5);
根据随机数选择(如,UE生成1个“0”到“1”间的随机数,当该随机数小于约定的门限值(如,0.5)的时候,UE选择随机接入过程类型1,否则选择随机接入过程类型5);
根据指定优先的随机接入过程类型(如,UE根据网络侧指示或协议约定,对于有数据发送的随机接入过程,优先选择随机接入过程类型1)。
更进一步地,随机接入资源的选择规则根据规则1(1.1或1.2)和规则2(2.1或2.2)和规则3(3.1或3.2)进行任意组合。具体选择规则同上,在此不再重复描述。

如,规则1.2+规则2.2:UE先选择随机接入资源对应的随机接入过程的类型,再选择随机接入资源对应的载波,再选择随机接入资源对应的信号。(或,UE先选择随机接入过程的类型,再选择随机接入资源对应的信号,再选择随机接入资源对应的载波)。
更进一步地,对于规则1.1,当UE根据“多个上行载波的随机接入资源选择规则”选择的载波数量为多个的时候(如,UE配置了3个上行载波,小区RSRP的测量门限值为-80dBm,UE测量的小区RSRP测量结果为-60dBM,超过该门限值可用于随机接入信号发送的载波为2个),则更一步的UE的随机接入资源的选择规则包括以下任意一种:
UE先根据“随机接入过程类型的选择规则”选择对应的随机接入过程对应的随机接入资源,如果UE的随机接入资源对应的载波数量仍然为多个,则UE选择其中1个载波;
UE先选择其中1个载波,再根据“随机接入过程类型的选择规则”选择对应的随机接入过程类型。
更进一步地,对于规则1.2,当UE根据“随机接入过程类型的选择规则”选择的随机接入过程类型对应的随机接入资源,该随机接入资源对应的载波为1个,则更一步的UE的随机接入资源的选择规则包括:
UE不再执行“多个上行载波的随机接入资源选择规则”。
如,UE选择的新两个随机接入过程对应的随机接入资源都在载波1上,此时UE不再执行载波选择规则。
这是为了避免,当UE的小区1测量结果小于门限值不选择载波1的情况(即,规则选择冲突),导致随机接入过程失败。
更进一步地,对于规则2.1,当UE根据“信号的选择规则”选择的信号为多个的情况(如,UE配置3个SSB对应的随机接入资源,超过网络配置RSRP门限值的SSB为2个,则UE选择的SSB为2个),则更一步的UE的随机接入资源的选择规则包括以下任意一种:

UE先选择其中1个信号,再根据“随机接入过程类型的选择规则”选择对应的随机接入过程对应的随机接入资源。
如果,该信号只用于其中1种随机接入过程类型(如,只用于随机接入过程类型1),则UE可以不再根据“随机接入过程类型的选择规则”选择对应的随机接入过程对应的随机接入资源。
这是为了避免当UE根据“随机接入过程类型的选择规则”无法选择该信号对应的随机接入资源的情况(即,规则选择冲突),导致随机接入过程失败。
更进一步地,对于规则2.2,当UE根据“随机接入过程类型的选择规则”选择的随机接入过程类型对应的随机接入资源,该随机接入资源对应的信号为1个,则更一步的UE的随机接入资源的选择规则包括:
UE不再执行“信号的选择规则”。
如,UE选择的随机接入过程类型1对应的随机接入资源对应于SSB1,此时UE不再执行信号选择规则。
这是为了避免,当UE的小区1的SSB1的测量结果小于门限值不选择SSB1的情况(即,规则选择冲突),导致随机接入过程失败。
更进一步地,如果UE根据上述选择规则1.1或1.2,对于随机接入资源配置在多个载波的情况,如果UE无法选择到任何的载波(如(规则冲突),UE先根据载波选择规则选择载波1,但是当UE执行随机接入过程类型选择规则后,UE选择的随机接入过程类型对应的随机接入资源不在载波1上), 更一步的UE的随机接入资源的选择规则包括以下任意一项:
UE再执行一次“多个上行载波的随机接入资源选择规则”(即,忽略该选择结果,再次进行载波选择);
UE再执行一次“随机接入过程类型的选择规则”(即忽略该选择结果,再次进行随机接入过程类型的选择);
UE选择1个载波(如,可以为任意基于竞争的随机接入资源对应的载波)。
更进一步地,如果UE根据上述选择规则1.1或1.2,对于随机接入资源配置在多个载波的情况,如果UE无法选择到任何的随机接入过程类型(如(规则冲突),UE先根据载波选择规则选择载波1,但是当UE执行随机接入过程类型选择规则后,UE选择的随机接入过程类型对应的随机接入资源不在载波1上。),更一步的UE的随机接入资源的选择规则包括以下任意一项:
UE再执行一次“多个上行载波的随机接入资源选择规则”(即,忽略该选择结果,再次进行载波选择);
UE再执行一次“随机接入过程类型的选择规则”(即,忽略该选择结果,再次进行随机接入过程类型的选择);
UE选择1种随机接入过程类型(如,可以为任意基于竞争的随机接入资源对应的随机接入过程类型)。
更进一步地,如果UE根据上述选择规则2.1或2.2,对于随机接入资源配置了对应的信号的情况,如果UE无法选择到任何的信号(如(规则冲突),UE先根据信号选择规则选择SSB1,但是当UE执行随机接入过程类型选择规则后,UE选择的随机接入过程类型对应的随机接入资源不对应于SSB1),更一步的UE的随机接入资源的选择规则包括以下任意一项:
UE再执行一次“信号选择规则”(即,忽略该选择结果,再次进行随机接入资源对应的信号选择);
UE再执行一次随机接入过程类型的选择规则”(即,忽略该选择结果,再次进行随机接入过程类型的选择);
UE选择1个随机接入资源对应的信号(如,可以为任意基于竞争的随机接入资源对应的信号)。
更进一步地,如果UE根据上述选择规则2.1或2.2,对于随机接入资源 配置了对应的信号的情况,如果UE无法选择到任何的随机接入过程类型(如(规则冲突),UE先根据信号选择规则选择SSB1,但是当UE执行随机接入过程类型选择规则后,UE选择的随机接入过程类型对应的随机接入资源不对应于SSB1。),更一步的UE的随机接入资源的选择规则包括以下任意一项:
UE再执行一次“信号选择规则”(即,忽略该选择结果,再次进行随机接入资源对应的信号选择);
UE再执行一次随机接入过程类型的选择规则”(即,忽略该选择结果,再次进行随机接入过程类型的选择);
UE选择1种随机接入过程类型(如,可以为任意基于竞争的随机接入资源对应的随机接入过程类型)。
对于上述方法,UE选择了对应的随机接入过程类型后,再在该随机接入过程类型对应的1个或多个随机接入请求资源上选择特定的随机接入请求资源发送随机接入请求信息。
如,UE选择了随机接入过程类型1,则UE在随机接入过程类型1对应的PRACH资源上选择特定的PRACH资源发送随机接入请求信息Msg1。
如,UE选择了随机接入过程类型2,则UE在随机接入过程类型2对应的PRACH资源(和/或PUSCH资源)上选择特定的PRACH资源(和/或PUSCH资源)发送随机接入请求信息MsgA。
采用本公开所述的方法,可以合理的控制UE在有数据发送的随机接入过程和没有数据发送的随机接入过程间,以及在不同类型的有数据发送的随机接入过程间进行选择,从而提高随机接入过程的资源利用效率。
